GAS-ENRICHER.

SPECIFICATION forming part of Letters Patent No. 557,086, dated March24, 1896.

Application filed January l5, 1896. Serial No. 575 ,635. (No model.)

To @ZZ whom, t may concern:

Be it known that I, GEORGE G. SCHEOEDEE, a citizen of the United States,residing at Vashingtondn the District of Columbia, have invented certainnew and useful Improvements in Gas-Enrichers and I do declare thefollowing to be a full, clear, and exact description of the invention,such as will enable others skilled in the art to which it appertains tomake and use the same, reference being had to the accompanying drawings,and to the letters of reference marked thereon, which form a part ofthis specification.

The invention relates to improvements in gas-enrichers, the main objectsbeing to provide an apparatus of simple construction whereby the gas maybe caused to ascend through an oil sufficiently far to permit it toabsorb enough of the oil to give it the desired degree of illuminatingpower, and to so construct and arrange the parts of the apparatus thatthe amount of oil absorbed by the gas part of this specification, Figurel represents a perspective view, sectioned vertically andlongitudinally, of a carburetor embodying the invention. Fig. 2represents a detail side view, partly in section, of the inlet-pipe,iioat, and attachments. Fig. 3 represents a plan view of the parts shownin Fig. 2. Fig. 4f represents a vertical sectional detail view of theoil-feeding device hereinafter described.

Referring to the drawings by letter, A designates the box or case of theapparatus of rectangular shape and divided by the vertical perforatedpartitions c a. into the three compartments or chambers B, B and B2.

i B designates the oil-chamber into which the gas passes through thevertical pipe h, the

lower end of'which is attached to and opens into the outer end of thecase A and chamber B at a suitable point at or near its center, thisattachment being made by a suitable coupling-piece hereinafter morefully described. The upper end of the pipe b is adapted for attachmentto a pipe from anyproper source of gas-supply and is provided with avalve b to regulate the inward iiow of gas.

C designates the coupling-piece referred to, the construction of whichis plainly shown in Figs. 2 and 3. The said coupling-piece comprises thevertical portion c, internally threaded to receive the meetingexternallythreaded end of the pipe b and an internal horizontal portiond, having at lits end the hollow cylindrical socket c2 to form a jointwith the adjacent end of the vertically-swinging inlet-pipe D. The saidend is enlarged and formed into a cylindrical hollow head d and isconnected by a short tubular piece d' to the cylindrical socket c2, sothat gas will iiow freely through the joint at whatever inclination thepipe D may stand. The pipe D extends a suitable distance inward and hasits inner end d2 curved downward and secured to the hemisphericaldeflecting-plate E, into which it opens near the top thereof, the saidplate being notched around its edge at e e to permit the gas to escapemore readily thereunder and to cause it to break up into globules orparticles, so that it will come into more intimate contact with the oiland, consequently, take up more thereof.

F is a float of any suitable form and light material, but preferablyhollow and globular and of sheet metal, provided on its top with a knobf, the purpose of which is hereinafter explained.

G is a short, vertical, externally-threaded nipple rising from the topof the casing A 'at a proper point, and II is a tubular cap, internallythreaded at its lower end to'screw down on said nipple. Above thetubular cap II is a vertically perforated or tubular en-Y largement I,provided with the transverse cutoff cock c', and above thesaid'enlargement is the funnel or hopper J, provided with the IOOtransverse removable screen or sieve j, as shown in Fig. 4. The cap II,enlargement I and .hopper .I are preferably made in one piece, as shownin Fig. 4.

K, Figs. l and 4, is a tube passing through the nipple G and having aiange 7o surrounding its upper end and resting on the nipple to hold itfrom falling inward. The tube K is perforated at suitable points k t,and has its lower end closed by the disk k2, against which the knob f ofthe iioat F is adapted to impinge.

L is a tube rising vertically from the top of the casing A,communicating with the purifying-chamber B, and provided on its top witha suitable feeding-funnel Z, and below said funnel with a stop cock orvalve ZC By means of the funnel Z and tube L the Sponges in the chambermay be kept moist or saturated with any purifying liquid.

M is the outlet-pipe for the gas after it has been enriched andpurified. The said pipe leads from the upper part of the compartment B2to any proper point of storage or consumption and is controlled by thevalve m at a suitable point near the apparatus. This compartmentprovides a storage-chamber for the enriched and puriiied gas, so that afree flow through the outlet-pipe may be had, which would not be thecase if the mouth of said pipe impinged upon the sponge of thepurifyingchamber.

In operation the oil is fed to the chamber B through the funnel J,passing through the openings 7c 7:.' into said chamber. Now when thechamber has a sufficient quantity of oil, the latter raises the float Ftill the knob f presses up the disk 7g2, so that the apertures 7s aremoved up into the nipple or sleeve G and communication through themclosed, thereby cutting off the feed from` the funnel or hopper J. Thenthe level of the oilin the tank sinks, the disk 7a2 falls, the saidapertures are uncovered and the automatic feed again begins.

By means of the hopperl and pipe L asuitable heavy oil carrying apurifying agent, such as powdered alum, may be fed to the sponge in thechamber B', so that the sponge is at all times suitably moistened, andat all times carries the purifying agent in proper quantity to absorb orremove impurities, such as coal-tar, by a process like that offiltration.

I am aware that gas-enrichers or carburetors having compartmentsseparated by p erforated partitions have been used, and such I do notdesire to claim, broadly; but

Vhat I claim as new, and desire to secure by Letters Patent, is-

I. In a gas-enricher the combination with the oil-compartment, of avertically-swinging gas-supply pipe entering said compartment, adelecting-plate and a float secured to the free end of said pipe, and anoil-feedingvalve communicating with said compartment and located in thepath of movement of the swinging gas-supply pipe, whereby the feed ofoil is cut off when the compartment contains the desired quantity,substantially as described.

2. In a gas-enricher, the combination with the casing divided byvert-ical, perforated partitions into an oil-receiving chamber, anoil-deliveringchamberand a purifying-chamber, situated between the oilreceiving and delivering chambers, of means for delivering a purifyingagent to the purifying-chamber, a vertically-swinging gas-supply pipeentering the oil-receiving chamber, and an oil-feed valve communicatingwith said chamber and located in the path of movement of the swinginggas -supply pipe, substantially as described for the purpose set forth.

3. In a gas-enricher, the combination with the tank, thevertically-swinging tube therein, adapted to receive gas from any propersource of supply, and the concave depending plate, attached to a properfloat and receiving gas near its upper edge, from the upper end of saidswinging tube, of the automatically-closing oil-feeding device,essentially composed of a vertical nipple rising from the top of thetank, at a proper point, the perforated tube, movable vertically in saidnipple, iianged around its upper end to prevent its falling through saidnipple, and having a closed lower end against which the top of the iioatimpinges when the tank has a sufficient quantity of oil; therebystopping the iniiow of oil through the perforations in said tube bymoving them upward against the inside of the nipple, substantially asspecified.

et. In a gas-enricher, the combination with the receiving-tank, thefeed-pipe opening into one end of the receiving-tank, the movablegas-pipe, free at its inner end, and pivoted at its outer end to asuitable coupling-piece secured to the inner surface of the outer end ofthe receiving-tank, and having communication through said coupling-piecewith the feed-pipe and the float, substantially as described, secured tothe inner end of the movable gas-pipe; of the oil-feeding device,composed of the nipple G, tube II having a suitable stop-cock andfeeding-funnel, at its upper end, and the perforated tube provided withthe iiange 7o at its upper end and disk 7a2 at its lower end; allconstructed and arranged substantially as shown and described for thepurposes specified.

5. In a gas-enricher, the combination with the casing, the gas-deliverypipe secured to the outside of the casing, the vertically-swing'- inggas-delivery pipe, pivoted at its outer end, to a bracket secured to theinner side of the end of the casing and communicating through saidbracket with the outside delivery-pipe and the float attached to theinner, free end of the swinging delivery-pipe and composed of the hollowsphere F and hemispherical delecting-plate E notched at c, e, in itsedge,
